Re: I have a HP Photosmart 6510, I replaced all my ink cartridges but now it won't print or copy,

we tried all that, do you think there is a problem with the black ink well that it won't print or copy just disburses blank pages? appreciate your help....it was printing before I replaced the black ink and the colors but after I did that, I ran all the print "jobs" under toner tools and prints all colors but no black...is the toner indication on toner screen supposed to be black for quantity? I tried two separate iblack ink cartridge and the same results for both, thought maybe the first one was just disfunctional but not two in a row....

Re: I have a HP Photosmart 6510, I replaced all my ink cartridges but now it won't print or copy,

I have tried with sucess serveral times sumerging the cartridge in isopropyl alcohol for about 5 mins (only the print heads) if you decide to try this PLEASE MAKE SURE that the cartridge is completely dry before you reinstall in the printer.

next,

I personall will of course only if you can, purchase another cartridge to make sure is not a ahrdware related issue,

I will reach out to some folks in here to see if they have other suggestions or knowledge of this or similar issues.

Hope this helps!

Re: I have a HP Photosmart 6510, I replaced all my ink cartridges but now it won't print or copy,

The very same thing happened to me. I replaced the black ink cartridge. Now it will not print even after I completed all those steps. I bought the ink cartridge from HP on line BUT the printer indicated that a cartridge was damaged. I put the old cartridge back in and it stopped complaining HOWEVER it still will not print anythng at all.
